Your Photos library holds all your photos, albums, slideshows and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Library and use Optimise Mac Storage, or move your photo library to an external drive.
Before you start, make sure that you back up your library.
Prepare your drive
You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled).1 Find out how to check the format of your external storage device.
Mar 18, 2020 In the Finder, go to the external drive where you want to store your library. In another Finder window, find your library. The default location is Users username Pictures, and it's named Photos Library. Drag your library to its new location on the external drive. To do so, open 'iPhoto' on your Mac and select all your photos to transfer. Click 'File' menu and select 'Export' option. A 'File Export' window opens up. Select 'Original' option in 'Kind' and 'Event Name' option in the 'Subfolder Format' and then click 'Export' button.
To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.

- Dec 11, 2018 If you just have your photos in a folder on your Mac, all you need to do is plug your external drive in and move them over. If you’re using another app that maintains a library, you’ll have to configure things within that app.
Delete original library to save space
After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.
In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disc space.
Open another Photos library
If you have multiple libraries, you can open a different one like this:
